What defining feature separates the genus *Jynx* from the various genera of true woodpeckers?
Answer
The tail structure, specifically lacking the stiffening adaptation for vertical bracing
The classification into the genus *Jynx* is fundamentally based on morphological differences that reflect distinct behavioral niches within the broader woodpecker lineage. The most salient feature setting *Jynx* apart is the absence of specialized tail feathers that are stiff and pointed, which true woodpeckers use as essential props against vertical surfaces. Because wrynecks spend less time bracing vertically on bark—due to their preference for ground foraging and clinging horizontally to branches—they evolved away from this bracing necessity, resulting in softer tail feathers that lack rigidity.
